Antibacterial Agents

September 20, 2016

Expert: Rolf Halden, Ph.D., P.E.

Did you know that some products claiming to kill germs may actually be harming your health? The antibacterial agents triclosan and triclocarban are common in consumer products, such as soap, lotion, and toothpaste. But a growing body of research shows these antibacterial agents are linked to many adverse health effects, including endocrine disruption and antimicrobial drug resistance. In this podcast with Rolf Halden, we discuss what the science is telling us about the impacts of triclosan and triclocarban, the recent FDA decision to ban their use in hand and body washes, and what consumers need to know.


Rolf Halden

Rolf Halden, Ph.D., P.E., is a professor at Arizona State University (ASU) in the School of Sustainable Engineering and the Built Environment as well as Founding Director of the Biodesign Center for Environmental Security, the Human Health Observatory (HHO), and the National Sewage Sludge Repository at the ASU Biodesign Institute.

Halden is a noted expert in determining where in the environment mass-produced chemicals wind up, their impact on human health, and how to remove them from contaminated water resources, aquifers and agricultural soils. Toxins of interest include dioxins, anti-bacterial products, pharmaceuticals and personal care products (PPCPs), organohalides, problematic plastics and their additives, as well as pesticides – all having potential health impacts, including adverse birth outcomes, inflammation and increased risk of cancer.

He has provided scientific updates on environmental and human health concerns linked to antimicrobial agents to the Food and Drug Administration (FDA), Environmental Protection Agency (EPA), the National Academies, and U.S. Congress.
